After a unsuccessful arm system in '05 we rigged up our arm design with a multi positional pneumatics system and it worked surprisingly well with heavy use and only two tanks on board the compressor was strong enough to keep up with the load. For a game like this where you will only need two main positions for an arm system, a multi-positional pneumatics system for your arm is a very good option and far easier then implementing a beefy motor to handle the load. Of course there are negatives, the big one being bouncyness, but with a little creativity these problems can be solved.
We have also had good experiences using variable positioning pneumatics. We discovered last year that if we couple the pneumatic cylinder with a gas spring (i.e. like the ones that hold that hatch up in a hatch back car) we could get even more control and dampen any drifting and bounciness.
